OpenAI is rolling out ChatGPT Health to all U.S.-based users over 18 across all plans, expanding a feature that allows users to connect medical records and health-tracking data to the chatbot1,2.
The launch follows a testing period that began in January, during which users could integrate data from services such as Apple Health, Function, and MyFitnessPal through a dedicated health hub. Users can also connect medical records from hospital systems including Epic and Oracle Health, and health platforms such as One Medical and Function Health.
A key change in the general rollout: health data is no longer confined to a dedicated hub. Users can now draw on connected health information across all ChatGPT queries. OpenAI said that during testing, 70% of health-related queries took place outside the dedicated hub, prompting the broader integration.
Health-related query volume has grown from 230 million per week — the figure OpenAI cited at the feature's initial launch — to 300 million per week.
The rollout is accompanied by performance claims that drew internal tension during an OpenAI briefing. Ashley Alexander, OpenAI's vice president of health product, said the company's models "are now capable of reasoning at levels that are better than clinician level". Karan Singhal, OpenAI's health lead, said during the same briefing that he would "temper" that claim, noting that "there have been individual studies" supporting the comparison.
On the model side, OpenAI said its smallest model from its latest release, GPT 5.6-Luna, outperforms GPT 5.5 on health-related queries.
ANALYSIS The gap between Alexander's and Singhal's characterizations is notable: one executive made an unqualified claim of better-than-clinician reasoning, while the other walked it back in the same briefing, pointing only to individual studies rather than systematic evidence.
The announcement arrives one day after a Florida-based pastor sued OpenAI, alleging the chatbot gave a near-fatal suggestion not to consult a doctor.
ANALYSIS The timing of the broad U.S. launch against an active lawsuit over health advice underscores the liability exposure OpenAI faces as it positions ChatGPT as a health-information tool for a general consumer audience.
